To all whom 213 may concern: Be it known that We, Gsonon C. Surrey, ISAAC W. CROWL, and JUHN U. Hmineno,

1 citizens of the United States, residing at a condenser of novel. constriiction which is adopted for condensing from the fQlOdHCiZS ofv combustion, particularly those derived from a stump, the valuable products carried by the roducts of combustion treated by the con enser.

Our invention consists in the novel condenser whether used in connection with the stump burning apparatus, or, in any oonnection where it is necessary or desirable to cmploy a condenser for products of combustion.

In the accompanying drawings: Figure 1 is ,a perspective showing the condenser in .use in connection with a stump burner; and

Fig. 2, a vertical section through the con-' denser. I

In our oo-pendingep licetion, Serial E0, 761231, We have claime apparatus for conducting internal combustion in the stump,

without regard to how Valuable parts, such as tar, acids, etc., existing in the products of combustion are condensed therefrom. ter of tho'stump l c hole 2 is bored down from the upper face thereof, 2i suitable dis tonce, say ten or twelve inches below the level of the eorth outside the stump. Asp other hole 3 is then bored into the stump in, a. general lateral direction, commencing shout the level of the earth and inclined downwardly so that it will intersect the hole 2 at or 'near'the lower end. thereof. A fire is then started, by any suitable means or in any referred manner otor about the point 2* w ere the holes 2 and 3 intersect and the combustion is allowed to continue until the ugper end part oil"; the hole 2 has become slightly enlarged. A. pipe 4, preferably oi: metal, and provided with ony suitiihle oil valve or controlling device 5 at its outer art, is inserted in the hole.3 to within a ew inc esof vllere holes 2 and 8 intersect at 2". his pipe constitutes o draft pipe and the amount of air admitted to the fire at 2 maybe regulated by the mice 5. At

and collected Preferably, at 01 near the cen-.

or about the 'ine the e 15.? inserted, a pipe 6, preferably of motel, and ofsoitahle diameter, soy two inches, more or less, issorted inthe hole 2 after the said. hole has become slightly enlarge-cl. at it too by as the tire. The nine Sis entered i .i flzolo 2 to :1 distance within inches shove the point 2, upper end of pipe ex- 1 tending shove the top of the stumgii A flat sheet of metal. I is then fosteneei to the top as oft'ne stump h nails or other izistenings 7, or positioned thereon and it is presided with. any suitable means such as T engage the pipe 6 and {sieve 3hr 4:81 from dropping. The" plate 0 prevents fire from the point where pipe 6 ,pothe upper face of the stomp on. the stump from burning to any *p ieciehle extent shove the lower end of 1" pipe f by preventing draft through tii oi'eviously e Posed upper face of etu The foregong steps heen'toiren,

The hood is provided with :1 damper or valve 9 the admission of a; vany desired emountcof air to mix-with the prodnets of combustion corn '5:- of the pipe 6 for the purpose o ucte ofconihnstion and. to v sequent comiensetion icon 2 An elbow 19 connects open uppc of the hood 8 to genes y 3 posed pipe ii, said. pipe one. elbow 0 being preferabi several inches in dimneter. The pipe 11 1S slightly inclined ovided e5 with-1i take-oi: faucet 12 from oh the condensed liquids derived from the peeducts of combustionmey be drawn off, the inclination of pipe 11 causing such liquids of condensation to flow by gravity to the oo tap or faucet 12. An elbow l0- anci on upright pipe 11 pass the products of combos tion into the lowest section oi the con denser 13. i

The condenser i3 is composed; of on upper section 18* and a lower section iii 'which are preferably cylindrical, the up escoping into the lower sect supported thereby. The ices} have closed upper and iOWGET 'tion telescopin "tubes of the ot er section.

The lower section has brackets 16 into which legs 17 are screwed. The legs may be of iron pipe. The lowermost section has a take-0d pipe 18 controlled by a 'valve 19 through which the condensed liquids are drawn off from the condenser 13 independently of those drawn oil by the faucet 12.

The respective sections 13, 13*, have air draft tubes 20 extending therethrough from end to end, the ends of the tubes of one secat 21 with the ends of the The lower section 13 has a conical hood 22 arranged above the socket 23 which re ceives the end of pipe 11". As the products 'of'combustion pass into the pipe 11 and issue from the upper end thereof, they strike against the hood or bathe 22 and are spread downwardly and around the air draft pipes 20 and, due to the circulation of air through these pipes, the products of combustion are cooled and the condensable parts thereof,

such as acids, tar, etc, fall to the bottom of section 13" and may be drawn off through the pipe or spout 18. The non-condensable gases and the smoke pass from the condenser by a drop pipe 24; which is carried by the upper section 13 and has its lower end 95 located a short distance above the hood 2 2. The smoke pipe 24 may be provided with a suitable valve or damper 26. As soon as the fire has gotten well undeesvay in the center of the stump 1, the draft through the pipes 4 and 15 is partially cut off by regulating the valves or dampers 5 and 26. The stump then acts as a retort and the smoke and gases generated by the combustion therein pass into the pipe 11 and the condenser where they are condensed. The condensables may be taken off through the faucets or spouts 12 and 19.

.Tlhe apparatus may be made in, several sizes adapting it to stumps of different sizes. Disposing the condenser in lateral offset relation to the stump prevents it from v becoming heated from the direct heat from the stump and assists in cooling and condensing the gases. The condenser may be enlarged to any desired extent by interposing between the upper and lower sections 13 and 13*, intermediate sections which have no upper and lower heads, but are composed solely of draft pipes like the pipes 20, an extension of the pipe 24-, and a surrounding shell.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

1. A sectional condenser composed of shells, tubes connecting said shells together,

means for admitting products of combustion to the condenser, means fortaking oif smoke and non-condensable gases therefrom, 1 and means for removing the condensables from said condenser.

2. A condenser composed of shells having" air draft pipe sections, said shells and air draft pipe sections being fitted together, m ans for admitting products of combustion to'the condenser, means for taking ofi' smoke and noncondensable gascstherefrom and means for removing the condensables' from said condenser. r i z 3. A condenser composed of a shell, air draft tubes extending thcrcthrough, means for admitting products of combustion to the interior of the shell, a hood or bafl'le-for spreading the products of combustion as they enter the shell, means for letting oft" they enter the shelle 1 in testimony whereofiwve hereunto al'fix iur signatures in presence of two witnesses.
